Remote automatic travel system, wireless communication method, and moving body device

Abstract

Provided is a remote-type autonomous traveling system in which a mobile body apparatus that has at least one camera and a remote operation terminal are communicatively connected. The mobile body apparatus includes an acquisition unit that acquires environmental information, a determination unit that determines whether or not a critical state is attained, based on the environmental information, and a communication unit that transmits data of an image that is captured by at least the camera to the remote operation terminal through a first wireless base station that is capable of providing a macro-cell, by performing communication in compliance with a first communication scheme, according to a result of the determination by the determination unit that the mobile body apparatus is in the critical state. The remote operation terminal transmits a control signal for remotely causing the mobile body apparatus to travel autonomously, through the first wireless base station, according to the data of the image that is captured by the camera, which is transmitted from the movable body apparatus.

Description

TECHNICAL FIELD[0001]The present disclosure relates to a remote-type autonomous traveling system and a wireless communication method that remotely causes a movable body apparatus (for example, a vehicle) to travel autonomously and relates to a mobile body apparatus that is a target for remote autonomous traveling that is caused by the remote-type autonomous traveling system.BACKGROUND ART[0002]An Intelligent Transport System (ITS) (road traffic system) generally refers to a new road traffic system that is newly established as a system in which a person, a road, and a mobile body apparatus (for example, a vehicle) are integrally involved using the state-of-the-art Information Technology (IT) for the purpose of improving the road traffic safety, the transportation efficiency, and the comfortability and so on. For example, as disclosed in NPL 1, regarding the ITS, various studied on the realization of an autonomous traveling system for the mobile body apparatus (for example, the vehicl...

AI Technical Summary

Benefits of technology

This approach effectively suppresses the increase in allowable delay time for image data transfer and prevents system capacity insufficiency in macro-cell base stations, ensuring efficient remote operation with reduced communication costs and infrastructure complexity.

Problems solved by technology

Because of this, it is possible that the vehicle is remotely caused to travel.

Because of this, it is difficult to accomplish the shortening to the delay time (for example, the order of 10 ms) that is allowed for the transfer of the pieces of data of the captured images.

Thus, there is a likelihood that a system capacity (more precisely, a value of the sum of capacities for pieces of data that are handled in the macro-cell) of the macro-cell in the macro-cell base station will not be sufficient.
